Emis Maint Light??

[Squeegy410]

My Emission Maintance light started coming on right when it first started getting cold. Is this something to worry about or is it normal?

It is set to go off around 75k miles i think. It is just to tell you its time to replace your O2 sensor. They can't be reset so just unplug it.

Its a little clear box under the dash, glove box side. Looks like a clock for a bomb. Tried finding a pic of it, but came up empty.

Mine is on the drivers side. I think it was originally boled up against the side near the radio/heater. It is now stuffed up on top of the column.

ehhh You could be right Jim. I know it is on the very lower piece of the dash. Looks different when its off the truck haha.

yup, should be on the drivers side towards the center of the dash. It's just a timer, designed to go off and remind you that it may be time to change out the 02 sensor. The dash light doesn't actually mean that anything is wrong. :thumbsup:

I thought there was a way to reset it? Unplugging it turns the light out? If that doesn't work, you could just pull the bulb out of the cluster for it.

far as I know there is no way to reset the 90 and older timers. you have to buy a whole new timer. 91+ are resetable.

I'm amazed that 20+ years later, there are still so many MJ's out there that haven't turned 70-80k miles yet. :yes:

 

Here's a pic I stole (and modified ;) ) from the last maintenance light thread:

Jim, can you put that picture in the "picture thread" in the DIY section?

You can also buy the EMR Here. But, just why would you? I had a thread here about a week ago asking the same question. I thought of better things to spend $45.00 on. I also see them on eBay a lot but wonder if they are at 77,000 miles and I'd get the reminder a week after buying it. I keep an engine log so I can remember when to change oil and other routine maintenance along with parts numbers of replaced parts. It's a lot better system then an idiot light on the dash.

 

Mac...

good deal :D oh and my truck has 105k on it. whys the light just now going off?

[Squeegy410]

Finally nosed around and found the thing. Really easy fix. The wires were factory detachable. I suppose they expected everyone to unplug it. Thanks everyone :cheers:
